摘　　要：目的探讨分析中枢神经系统感染CT与磁共振(MRI)诊断的临床效果。方法选取2010年2月-2014年2月在医院因中枢神经系统感染治疗的45例患儿,每例患儿同段时间内(≤6h)行CT及MRI的数据分为研究组;45例患儿同时入院时做血病原菌培养和脑脊液涂片的数据为对照组,然后将研究组的CT和MRI数据分别与对照组的结果进行对比分析。结果 CT检查的符合率为53.3%,MRI检查的符合率为84.4%;CT与MRI图像符合率间的差异有统计学意义(P<0.05);CT检查病毒、细菌、其他病因阳性率分别为66.7%、20.8%、12.5%,MRI检查病毒、细菌、其他病因的阳性率分别为39.5%、34.2%、26.3%;CT与MRI图像在诊断病毒、细菌、其他病因导致感染差异有统计学意义(P<0.05)。结论 MRI在诊断中枢神经系统感染的阳性率明显高于CT;但是,CT在诊断病毒导致感染的阳性率明显高于MRI,而MRI在诊断细菌、其他病因导致感染的阳性率明显高于CT,若能将CT及MRI很好的结合于临床,能更有效提高中枢神经系统感染的临床诊断,值得临床参考。OBJECTIVE To explore the clinical effects of CT and magnetic resonance imaging （MRI） on diagnosis of central nervous system infections .METHODS A total of 45 patients with central nervous system infections who were treated in the hospital from Feb 2010 to Feb 2014 were enrolled in the study ,the patients who underwent CT and MRI in the same time period （ no more than 6 hours） were assigned as the study group ,45 patients for whom the blood culture of pathogens and the cerebrospinal fluid smear were performed at the admission to the hospital were chosen as the control group ;the data of CT and MRI of the observation group were compared with the re‐sults of the control group .RESULTS The accordance rate of the CT examination was 53 .3% ,the MRI examination 84 .4% ,there was statistically significant difference in the accordance rate between the CT and MRI （P〈0 .05） . The CT examination showed that the positive rates of the viruses ,bacteria ,and other causes of diseases were 66 .7% ,20 .8% ,and 12 .5% ,respectively ;the M RI examination indicated that the positive rates of the viruses , bacteria ,and other causes of diseases were 39 .5% ,34 .2% ,and 26 .3% ,respectively ,there was statistically significant difference in the diagnosis of infections induced by the viruses ,bacteria ,or other causes between CT and MRI （P〈0 .05） .CONCLUSIONS The MRI shows higher positive rate in diagnosis of central nervous system infections than CT ,however ,CT shows significantly higher positive rate in diagnosis of the infections induced by the viruses than MRI ,and MRI shows significantly higher positive rate in diagnosis of the infections included by bacteria or other causes than CT .The CT in combination with MRI may effectively improve the clinical diagnosis of central nervous system infections ,it is worthy to be promoted in the hospital .
